It features a solid carbide substrate with a multilayer MTCVD coating consisting of TiN, TiCN, and Al2O3, delivering wear resistance and thermal stability at the cutting edge. The insert has an 80-degree diamond shape, a 0.5 inch inscribed circle, a 0.0313 inch corner radius, and a 0.1875 inch thickness. The RN chip breaker geometry uses a chamfered and honed cutting edge with a negative rake angle, making it well suited to continuous and interrupted cuts in steel and stainless steel.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning, facing, and boring operations in production and job-shop environments. It is a direct fit in KENLOC-style toolholders that accept CNMG 432 inserts with a clamp-and-pin holding method. Primary target workpiece materials are steel (ISO P) and stainless steel (ISO M). With four usable cutting edges per insert and a neutral hand orientation, it is a flexible choice for both roughing and finishing passes where depth of cut does not exceed 0.1691 inches. Licensed machinists and CNC operators are the typical installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP40B grade with multilayer MTCVD CVD coating: TiN, TiCN, and Al2O3 for heat and crater wear resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (CNMG) insert shape provides a strong cutting edge geometry with four indexable edges\u003c\/li\u003e\n\u003cli\u003eRN chip breaker with chamfered and honed edge for controlled chip formation in steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eNegative rake angle and 0-degree relief angle suit rigid, high-feed turning setups\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding methods in KENLOC-style toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO insert standards for drop-in replacement use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-style CNMG 432 toolholders using clamp and pin clamping.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before indexing or replacing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert — do not over-tighten by hand. Inspect the pocket seat and locating pin for chips or wear before seating a new insert to ensure proper edge presentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG432RN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP40B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5077 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1691 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3 (Multilayer MTCVD CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2205 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5393244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739064074546,"sku":"5393244","price":182.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d42d9d5685df18993ebf34d8df8c5cc_68d0035a-1592-473e-922b-5f0955214de4.jpg?v=1788808758","url":"https:\/\/voomisupply.com\/products\/kennametal-5393244-cnmg432rn-kcp40b-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
